This chapter discusses the importance of Henry Jenkins’ work on participatory and convergence culture to critical engagement with cultural studies texts. Highly influenced by the work of the Birmingham Centre for Contemporary Cultural Studies on subcultures, Henry Jenkins argued in his book Textual Poachers (1992) for a need to take fandom and audience participation seriously. In contrast to elitist theorists who see fans as obsessive slaves to the culture industry, Jenkins understands active fan participation with cultural texts (such as Star Trek and the Harry Potter books and films) as a re-authoring of dominant narratives, bringing about new and alternative readings and, in the process, offering possibilities for the ‘democratisation’ of these texts. Through an exploration of ‘convergence culture’, Jenkins has brought the debate on fandom and audience participation up-to-date with an assessment of the internet and social media. For Jenkins, convergence is less about the technological merging of media appliances and more to do with consumer interactions with new (as well as old) media. Convergence encourages participation, with the internet remaining the chief medium through which grassroots participation and the potential re-authoring of texts can take place. The chapter concludes with an acknowledgement of some of the problems of increasing user participation with popular culture texts, including governmental legislative controls and the increasing dominance of media corporations in the construction and dissemination of news content.
